The Kassø Power-to-X (PtX) facility in Aabenraa, Denmark, has marked a significant milestone in the renewable energy sector by becoming the world's first e-methanol production plant to achieve ISCC EU certification. This recognition under the International Sustainability and Carbon Certification (ISCC) EU scheme highlights the facility's adherence to strict sustainability criteria, positioning the e-methanol produced at Kassø as a Renewable Fuel of Non-Biological Origin (RFNBO) in line with the EU's Renewable Energy Directive. The rigorous certification process involved independent verification of the facility's renewable electricity sources and the biogenic origin of the carbon dioxide used in production, ensuring the highest standards of renewable fuel production. With an annual production capacity of 42,000 tonnes of e-methanol, the commercial-scale operation at Kassø is now able to supply substantial volumes of renewable methanol to global off-takers. This renewable methanol, produced by combining renewable hydrogen with biogenic CO2, presents a sustainable alternative to traditional fossil-based methanol. The achievement of ISCC EU RNFBO certification is lauded by Rene Alcaraz Frederiksen, CEO of Solar Park Kassø, as a crucial step towards supporting climate action in Europe, particularly in sectors like shipping and aviation. The meticulous documentation of operational processes at the facility, ensuring the use of renewable electricity, biogenic CO2 origin, and adherence to strict mass balance and traceability requirements, underpins the classification of methanol at Kassø as e-methanol. This certification not only validates the renewable integrity of the e-methanol but also provides assurance to customers and stakeholders, reinforcing its role in the decarbonization of key industries and paving the way for broader adoption of e-methanol in the green fuels sector.
